A nice bug report, thank you. Turns out to be an obscure GADT case, and
another reason for switching to System FC.
I've fixed the STABLE branch, but I won't fix the HEAD because we're
about to move to FC so it seems hardly worth it.
BUT if we release the HEAD before the FC switch, we should apply the
patch from the STABLE branch.
Meanwhile, as a workaround, compile without -O. Or even just compile
Vector.Fast without -O
